Pr.6
1) Set "0" in
("0" is set as the default value for
2) When workpiece "W" moves toward the address increment direction, keep the current setting.
When workpiece "W" moves toward the address decrement direction, set "1" in
rotation direction.
3) Carry out forward run JOG operation again, and if "W" moves toward the increment direction, the
setting is complete.
1) Forward run pulse
(3) A phase/B phase mode
Forward run and reverse run are controlled with the phase difference of the A
phase (A ) and B phase (B ).
When the B phase is 90 ° behind the A phase, the motor will forward run.
When the B phase is 90 ° ahead of the A phase, the motor will reverse run.
